Application filed April 4,

My invention relates to improvements in snow removers, and the object ofmy improvement is to supply particularly for highway use, a snow plowofan improved andfefficient shape for forward propulsion in gathering snowanddelivering it obliquely laterallyto a distance or beyond the roadlimits in dumping it to clear the way for traflic. Another improvementcomprises mechanical means 10 for vertically adjusting the plow withself'- locking elements included, and a further'im-- provement is inproviding supporting run ners for the plow when in use, to be tiltablein securing said vertical -ad ustments.

15 I have accomplished the above objects the means which are hereinafterdescribed and claimed, and which are illustrated 1n the,

cent grooved sheave 22, thence forwardly and downwardly and including atension spring 31 to be there connected to a staple or other fasteningmeans 33 on the lower part of said bar 15. The chain is thus kept undertension.

To lift the plow 1 clear of street or other obstructions while travelingto or from a district to be cleared of snow, the operator on the truck17 may turn the hand-wheel 28 appropriately to cause the worm 29 torotate the worm-wheel 26 and shaft 24:,with its sprockets 23. The chains30 are thus moved to lift the plow while causing its runners 12 to toremove snow in their path.

The speed of the truck and plow may be regulatedat will to handle snowof different consistencies, and ordinarily are driven at a considerablerate in order to cause gathered snow to mount the side troughs 6 whereit is slightly compressed because of the rearward convergence of thetroughs, so that the traveling load is shot obliquely rearwardly to oneside of a road with momentum enough to deposit it on the right of waywithout the road surface, at least on one side. If the road is too wideto'cause the snow to be shot to both sides in clearingthe road, theapparatus may return along oneside of the way after clearing the otherside part thereof. The medial wall 10 serves in completing the divisionbetween such side troughsand in the diversion of snow into the troughs,especially while penetrating high drifts.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is: V

A snow plow, a vehicle to which the plow is connected for verticaladjustments, and mechanism mounted on said vehicle and connected to saidplow for vertically adjusting it, comprising a rotatable transverseshaft on the vehicle having a worm-wheel thereon, aworm-shaft meshingtherewith, a parallel rotatable shaft on the vehicle, said shafts havingsprocket-wheels on their outer ends and the second-mentioned shafthaving grooved sheaves thereon within its pair of sprocket-wheels, apair of like chains each having its ends connected respectively to anupper and lower part of the plow on one side thereof, the lower reach ofthe chain including an elastic element, one reach of each chain passingabout both sprocket-wheels on its i no side, thence around the sheaveonthat side.
